BOBBIN-HANDLING APPARATUS.

Specification of Letters Eatent.

Patented June a, 1913.

To all whom t may concern:

Be it known that I, BURT A. PETERSON, a' citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in BobbineHandlingApparatus, of which the following is a specification.

rllhe object of this invention is to produce means for sorting aconfused mass of bobbins into a desired arrangement and forexpeditiously placing the bobbins in orderly arrangement into magazinessuch, for example, as the magazine used in connection with portablespinning-frame doilers.

1n the accompanying drawings, Figure 1 is a side elevation of oneembodiment of my invention. Fig. 1 is a ragmental. view of a magazine,showin the arrangement of the bobbins therein. i 2 is a top plan view otthe apparatus. Fig. 3 is a sectional view taken in the plane of dottedline 3 3 of Fig. 1. Fig. 4 is a sectional view in the plane of line 4 4of Fig. 1. Fig. 5 is a section on line 5 5 of Fig. 1. Fig. 6 is asectional view illustrating the means for driv- ,ing the rotary rodscomprised in the mechanism. Figs. 7l and 8 are sectional views taken inthe plane of dotted lines 7 and 8, respectively, of Fig. 1. Fig. 9` is afragmental sectional View illustrating a means for supporting themagazine during the illin operation. Fig. 10 is a section on line 1c@ing. 3. y

While the invention may be embodied in means for filling various formsof bobbin magazines, the embodiment herein 'illus` trated is especiallyadapted for loading the character of magazine illustrated in sideelevation in Fig.1 and in transverse section in Fig..5. `As shown insaid figures,v

the magazine comprises two end Jframes4 1 and 2, andl two oppositemetallic walls 3 and 4 bent to provide partitions 5 and, and

partial walls 7 and 8. As indicated in Fig. V 5, the partitions` 5 areso arrangedas to form longitudinal Agrooves 9 wide enough to receiveonly'one bobbin tip, whereby thetips or' bobbins placed in the magaz1ne,are

bottom 10 (Fig. 9). As will be understood from'Fi 5, the magazine isadapted to contain our tiers of bobbins arranged with their tipsextending in the same general direction.

The embodiment herein shown of my invention is adapted to sort bobbinsinto four rows, with the tips of the bobbins extending in the samedirection, and to feed the rows of bobbins into a magazine.

rlhe supporting framework of the loader may be of any suitableconstruction, that herein shown including a cast frame c0nsisting of theu rights 11 and the transverse member 12 (Figs. 7 and 8), a bracket 13(Figs. 1 and 4) of less height than the uprights 11, and two parallelbeams 14 each secured to the upper ends of the uprights 11 and thebracket 13. Between the beams 14 are arranged in parallel spacedrelation a plurality of bars 15 secured at ltheir upper and lower endsto the transverse member 12 and the bracket 13 respectively, andextending to a point beyond said bracket. The width of the spaces orslots between the bars 15 is greater than the diameter of a bobbin-tipVbut is not the diameter of a bobbin-butt. Hopper walls 16, 17 and 18 aresecured to the upper portions of the beams 14. Members 19 and 20 (Fig.3) suitably secured in place and extending longitudinally of the bars 15between the transverse ymember 12 and the hopper wall 18 have the bars.Members 21 and 22 (Fig. 4) secured to the'bar's 15 extend from the hop;

per wall 18 to'thelower ends of the bars 15. In the lower end'of thehopper are provided spacesI 23 (Fig. 3) alined with the slots betweenthe bars 15 and of suiiicient size to permit the passage of a bobbinpositioned as indicated in saidigure. Guard plates 24 are secured tothebars 15 at opposite sides of theslotsbetween said bars. ...Rotatablymounted in grooves formed between the bars 15 and the members 19, 20, 21and 22 are-rolls 25, a portion of the periphery of each roll projectingbeyond the parts betweenwhich it lies, so as to contact and-supportbobbins extending through` the slots between. the bars 15 as indicatedin Fig. 3. `Bearings for the rolls 25 are provided" in the frame-member12. The rolls 25 may be driven by any suitable means as,

for exam le, a shaft 26 and spiral gearing 27 (Fig.

28 and 29 are tight and loose pulleys on the shaft 26, 30 is a drivebelt, and 31 is a belt-shifter fork operated by means of a slidable rod32.v

The rolls 2 5 are rotated in the directions to cause the portions oftheir peripheries which are adjacent to the slots between the barstomove upward. As shown in Fig. 9, the rolls 25 extend to the lower endsof the bars 15.

Adjacent tothe lower ends of the bars 15 is means for supporting amagazine. The 15 supporting means herein shown, by way of example,'comprises a table 33 inclined at the same angle as the series of bars15 land provided with side lrails 34. The table 33 extends up beneaththe series of bars 15 sufficiently far to permit of sliding the magazineonto the ends of said bars until the latter are adjacent to the bottomof the magazine. The bars 21 are grooved as at 35 (Fig. 5) toaccommodate the partitions 6.

Any suit-able means may be employed t0 releasably hold the magazine inthe position indicated in Figs. 1, 2 and 9, as, for instance, a hook ordetent 36 fixed upon a suitably supported rock shaft 37 extendingtransversely of the table 33. The detent 36 is located in position tounderlie the end frame 1 of the magazine. When the magazine is to bereleased, the operator withdraws the detent by rocking the shaft 37through the medium of the handle-portions 38. A weight 39 normally holdsthe detent 36 in operative position, this position being determined by apin 40 (Fig. 5) stopping against suitable fixed parts 41.

40 In use, an empty magazine is placed upon the table 33, slid up ontothe bars 15, and locked in position by means of t-he detent 36. Motionhaving been communicated to the drive shaft 26, a quantity of bobbins isplaced in the hopper. By reason ofthe inclination of the bars 15, theytend to slide or roll down to the lowest portion of the hopper, and 'indoing so the bobbins quickly assume a position in line with the bars,whereupon the tips of the bobbins swing down into the spaces betweensaid bars. The bobbins thus arrange themselves in four rows, in thepresent embodiment with their tips extending downwardly. )Vhen in thisposition the bobbins rest in contact with the rolls 25, which rolls,accelerate the gravitational movement of the bobbins and prevent theirbindin and sticking between the bars 15. The bo bins thus descend, theforemost ones a0 stopping against the bottom of the magazine, and othersstopping against those in front, until the spaces between the bars 15are'completely filled up to a point above the magazine. The operatorthen releases the i ,cetera se, ma, what, raiding the magazine so as tocontrol its downward movement, lio pushes the rows of bobbins down withthe magazine. As the bobbins leave the spaces between the bars 15, thebutts of the bobbins assume a staggered relation in the spaces betweenthe partitions 6 and side walls 8 (as shown in Fig. 1a), and thus takeup less room longitudinally of the magazine than they did when arrangedin single lile between the bars 15; therefore, the operator 75 pushessuliiciently long lines of bobbins down with the magazine so that thelatter shall be properly filled when clear of the bars 15. )Vhen themagazine has been withdrawn from said bars, it is turned into an uprightposition and set aside, and another magazine put in its place. Thedownward movement of the bobbins is at such a rate as to permit of thussubstituting magazines before any bobbins are discharged from the seriesof bars 15.

I claim as my invention:

1. In a bobbin-sorter, the combination ot two members arranged inparallel relation and spaced apart a distance greater than'thc 90diameter of a bobbin-tip and less than the diameter of a bobbin-butt,one of said members being a roll against which the bobbins bear, andmeans for rotating said roll.

2. In a bobbin-magazine loader, the com- 95 bination of a plurality ofinclined parallel rolls arranged to support between them bobbinsextending transversely of the rolls, means for supporting a magazine soas to inclose a portion of the rolls, and means for rotating the rolls.

3. In a bobbin-magazine loader, the combination of a plurality ofinclined parallel rolls arranged to support between them bobbinsextending transversely of the rolls, means for rotating the rolls, andmeans for normally supporting a magazine so as to inclose a portion ofthe rolls, the magazinesupporting means including a table inclinedsimilarly to the rolls and arranged adjacent to the lower ends of saidrolls.

4. In a bobbin-sorter, the combination of a set of spaced parallel bars,a hopper-like structure over a portion of said set of bars, and rollssupported by said bars and pre- 115 senting a portion of theirperiplieries in the spaces between said bars, said rolls being adaptedto support bobbins.

5. In an apparatus of the character described, in combination, aninclined series ot' 120 spaced parallel bars, a hopper-like structurethe bottom of which is constituted of the upper portion of said bars, aninclined table. the upper'portion of which extends beneath the lowerportion of said bars, said lower r2; portion of the bars being adaptedto extend within a magazine ositioned upon the upper portion of said)table, and means for locking a magazine in such position.

6'. 'In an apparatus of the character de- 130 lUO scribed, incombination an inclined series of spaced parallel bars, a bopper-likestructure the bottom of which is constituted f the upper portion of saidbars, an inclined table the upper portion of which extends beneath thelower portion of said bars, said lower portion of the bars being adaptedto extend within a magazine positioned upon the upper portion of saidtable, and means for lo locking a magazine in such position, said barsbeing of such length as to provide a space between the upper end of themagazine and the ,lower end of the hopper-bke structure for theaccumulation of sorted bobbins.

AIn testimony whereof I hereby aiix my signature in the presence of twowitnesses.
